87    
88    1  December 2006, Bari F. Cafagna
89    
90    NEW TAGGED VERSION: v4r9
91    
92    NEW ANTIPROTON ANNICHILATION CROSS SECTION
93    
94       The new cross section has been added by Sergio Bottai to the geisha code.
95    
96    30 November 2006, Bari F. Cafagna
97    
98    NEW TAGGED VERSION: v4r8
99    
100    BUG FIXED
101    
102       For some reason there was a conflict using FLUKA and the GARFILD
103       interface for the TRD. The file TRD_ATT.TXT was treated as flukaerr
104       file by the compiler. It is not clear why. The code was correct,
105       the logical units and names were not inconflict, but the compiler
106       assigned to them the same internal number. It may be a problem
107       related to the optimization phase. I did close the file just after
108       the read-out in GPDAT.F and commented out the closing in UGLAST.F
109    
110    
111    
112    November 2006, Bari
113    
114    
115    S4 GEOMETRY UPDATED:
116    The x and y dimensions have been corrected because they were wrong.
117    A container of aluminum has been added having walls of thickness equal
118    to 0.1 cm.  
119    
120    TOF POSITIONS DEFINITELY UPDATED:
121    S2 and S1 have been positioned again, after the simulation of the top plate.
122    Before now, the positions were put by hand based on the positions given by
123    Sergio Ricciarini in the document 'Main geometrical parameters of the PAMELA
124    sub-detectors' released by O. Adriani, L. Bonechi, E. Mocchiutti and
125    S. Ricciarini on the 20th of December 2005.. These positions were
126    lightly approximated because the thicknesses of the mylar and of the glue were
127    not considered in that document. Also the height of S3 has been modified as
128    suggested from the Naples PAMELA collaborators.
129    
130    ND GEOMETRY COMPLETED.
131    The He3 and the polyethylene (CH2) have been added to fill
132    the volumes NDTI and NDPB in the neutron detector. Leonov gave us the
133    details of these materials.
134    
135    TOP PLATE GEOMETRY ADDED.
136    The top plate geometry has been simulated as a rectangular window filled
137    with a mixture of titanium (90%), aluminum (6%) and vanadium (4%). It has been
138    put in a N2 box having the same planar dimensions of CATA. In this box there
139    are also S2 and CATA at the right positions. Then the top plate geometry has
140    been completed with other eight small volumes of titanium positioned at the
141    corners of the N2 box. Four of them are at the same height of CATA, the
142    other four are at the same height of S2. The simulated geometry of the top
143    plate is based on a simplified version of the CAD drawings.
144    
145    October 2006, Bari
146    
147    The geometry of the neutron detector has been updated. Some dimensions of some
148    volumes have been corrected and the aluminum cover and the aluminum boxes to
149    put the cables have been added. A new material, the cadmium, has been also
150    defined.
151    
152    September 2006, Bari
153    
154    SPHE and ND data card bugs fixed: the definition of the ND data card,
155    missing in the subroutine gpgeo.F, has been added; the meaning of the SPHE
156    data card has been changed. Before the correction the data card:
157    NDET 'SPHE' was used to delete the spherical top shell to substitute it with
158    a flat one.Now NDET 'SPHE' eliminates the whole container of PAMELA.
159    
160    
161    June 2006, Bari
162    
163    The center of the scintillator planes S22Y (variable ZPAMS22Y in gpdgeo.inc)
164    and S12X (variable ZPAMS12X in gpdgeo.inc) has been positioned at the
165    nominal height as measured in PAMELA (See the document: "Main geometrical
166    parameters of the PAMELA sub-detectors" by O. Adriani, L. Bonechi,
167    E. Mocchiutti, S. Ricciarini, 20 December 2005). Follows that the positions
168    of S21Y and S12X are higher than those in the cited document due to the fact
169    that in GPAMELA the thickness of the mylar has been considered while in the
170    document it has been neglected.
171    
172    
173    May 2006, Bari & Tor Vergata
174    
175    GIGANTIC RESONANCE FOR NEUTRON DETECTOR ADDED
176    
177       Routines to simulate the gigantic resonance of gammas in Tungsten
178       have been added.  The GPGIG routine is called in GUSTEP if a gamma
179       enter the calorimeter absorber.  This is the steering routine to
180       simulate the production of neutrons from gigantic resonance.  It
181       does checks on STEP lenght. If the range is smaller than the other
182       selected for that step, it does generate the neutron and stops the
183       gamma. Please note that the neutron has now a new particle
184       number. This is to tag the gigantic resonance neutrons.
185    
186    
187    May 2006, Bari & Florence
188    
189    CAL HIT STRUCTURE BUGS FIXED
190    
191       The maximum number of hit is now different for the two hit
192       structures: CALST and CALI. Vectors inizialization and HBOOK
193       ntple booking have been updated. The GPDCAL routine has been fixed
194       so to handle the case in wich hits stored are more than the maximum
195       number of hit.
196       In this case in the ntple up to the maximum number of hits will be stored.
197    
198    April 2006, Bari
199    
200    TOF GEOMETRY AND POSITIONS UPDATED AND NEW MIXTURES ADDED
201    
202       The TOF geometry has been modified. The following boxes have been
203       added: POL1, POL2 and POLY made of polystyrene, S11M, S12M, S21M,
204       S22M, S31M and S32M made of mylar, S1A, S2A and S3 made of air and
205       S1 and S2 made of aluminum. Each scintillator paddle has been put
206       in his mylar box and the other materials: air, polystyrene, and
207       aluminum have been added at their nominal positions.  According to
208       Naples people the araldite glue has been simulated has an air
209       gap. For this work two new materials: the Mylar (MYLAR) and the
210       polystyrene (POLYSTYRENE) with a density of 35 g/l have been
211       defined as a mixture.  The positions of the three bottom
212       scintillator planes that contain respectively the S12X, S22Y and
213       S32X paddles have been regulated according on their official
214       positions in PAMELA.
215    
216    Mar 2006, Bari
217    
218    GEN DATA CARD UPDATED
219    
220       To enable generation on a surface perpendicular to the XY plane,
221       GEN gata card has been updated addingh a new parameter: ZDGEN. This is
222       the dimension, along Z axis , of the generation surface. The Z
223       position will be randomply chosen according to: Z= ZDGEN*RNDM_NUMBER +
224       ZGEN, i.e. Z= GEN(6)*RNDM_NOMBER + GEN(3).
225    
226  Nov 2005, Bari  Nov 2005, Bari
227    
228    GUHADR AND GUPHAD UPDATED
229    
230       To use GCALOR package the hadronic routines have been updated. The
231       inizialization routine call CALSIG, while the other calls GCALOR.
232    
233    NEW GPKEY ADDED: GPCALOR
234    
235       This logical has been added to enable the GCALOR package. This flag
236       is set to true in GPDAT if the data card: HPAK, is set to
237       'GCAL'. The gpkey.inc has been update accordingly.
238
